Brittany Murphy Protected By Co-Star

Hollywood beauty Brittany Murphy has been warned to tone down her friendly personality by her British co-stars in upcoming movie Love And Other Disasters. The 8 Mile star is based in London all summer as she films the romantic comedy - and has found her warm southern manners are too 'nice' for the honest Brit cast and crew. Co-star, comedienne Catherine Tate says, "She's genuinely, incredibly sincere but I think in this country we take that with a pinch of salt. "She is genuinely adorable, but she will say to people who she doesn't know, 'Have an amazing day.' "We say to her, 'Seriously, people will think you are taking the mickey out of them if you say that with that level of sincerity because we don't really do that over here!.'"
